The computer turns on but:
• The monitor has no signal (both onboard and gpu)
• The mouse has no light
• The keyboard has no light
• The LAN port has no light
• LED power switch has no light but it activates and turns the PC on
• No error beeps
• The CPU heat sink fan is spinning
• The GPU fan is spinning
• The SATA hard drive is spinning
- Tried unplugging and replugging the peripherals several times: Failed
- Tried resetting the CMOS: Failed
- Tried cleaning the PSU: Failed
- Tried replacing the PSU with a surely working one: Failed
It may be that my motherboard already gave up, but I wanna know what exactly caused it for future reference; for the sake of education O_O. So here's what happened:
My aunt's old PC was still working until last night.. And today, it suddenly won't turn on with those symptoms I mentioned. Because of that, she started panicking badly (I mean badly) because all her works are there and she needs it RIGHT NOW, so instead of trying to fix the PC itself, I had to take her IDE hard drive and plug it into one of my currently healthy working computer just to retrieve the files.
Now my PC also broke with the exact same symptoms she has. Which immediately gave me the idea that there might be a "short circuit" somewhere in the HDD or the 4pin Molex that caused the motherboard to break? (maybe). I found no burns anywhere though, but that HDD stopped spinning and won't turn on anymore.
I want to know if I missed something and if it can still be fixed
-or- if the boards are totally broken, how did it happen? Is it a short after all?
It is really possible for old HDDs to cause the motherboard to break like that?
Thanks to anybody who can help explain
